Biomarkers of optimal protein and amino acid intake include whole body or tissue protein balance, circulating protein or amino acid levels, physiological functions (muscle strength, immune competence, insulin sensitivity, glutathione, and oxidative stress), and ultimately clinical outcome.
We have carried out a comparative analysis of wild-type Arabidopsis plants and the double mutant npq1lut2 in terms of mRNA levels, metabolite levels and physiological functions in response to conditions leading to oxidative stress.
The high potency of low concentrations of plasma peptide hormones indicates the necessity for quantitative detection of low-abundance plasma peptides, with the challenge of their high turnover and regulated levels in physiological functions.
Our observation that changes in feeding cycles affect diurnal variation in BP and HR indicates that the response to changes in metabolic cycles is not limited to the level of gene expression (i.e., clock and metabolic genes) but reaches the level of physiological functions (e.g., BP and HR).
Altitude residents descending from altitude to sea-level are characterised by a rapidly occurring water retention leading to increased PV. 4 7 When these subjects return to altitude after a short sojourn at sea-level, some physiological functions must 're-adapt' (eg, erythropoietin (EPO) secretion), while other functions are able to switch quickly to altitude conditions (eg, ventilation).
New paradigms are needed if we are to succeed in unravelling multifactorial genetic causation at higher levels of physiological function [17].
PITX2, TWIST1, and HSPB27 are statistically significantly related to time to recurrence Since PITX2 was not expressed in the normal BM and its expression in BM from stage II/III breast cancer patients significantly correlated with early recurrent disease development, we sought to determine the expression levels and physiological function in established breast cancer cell lines.
Since transiently increased gastrin levels have important physiological functions in the gastrointestine, while sustained high gastrin levels (hypergastrinemia) are related to pathophysiological processes [ 7, 8, 10, 14], it is of interest to examine how the duration of gastrin treatment affects gene expression and molecular responses.
These levels were chosen because they group genes according to processes at intermediate levels of biological integration, which can be readily interpreted in terms of implication in cell-, organd and organism-level developmental and physiological functions [ 53].
At the level of physiological function, it should be added that those cyclohexadienyl dehydrogenases that exhibit a very substantial preference for prephenate are for all practical purposes prephenate dehydrogenases, even though they carry a formal designation of TyrAc or TyrAc_Δ.
Specifically, we demonstrated that falls-related self-efficacy was independently associated with gait speed among senior women after accounting for age, physical activity level, and relevant physiological functions [ 21].
